AbstractMorphologies of hydroxyapatite (HAp) powders have influence on the mechanical properties of HAp/polymer composites. In this paper we reported a synthetic route for nanospherical and ultra long fibrous HAp powders and compared the influence of HAp morphologies on composite mechanical properties. HAp fibers with the length of similar to 250 mu m along c-axis direction and nanospheres with the diameter of similar to 80 nm were produced, respectively, in the acidic solution containing glutamic acid and in the alkaline solution containing polyacrylic acid. The ultra long HAp fibers synthesized were used to reinforce biodegradable chitosan biomaterials with the significant improvement of bending strength because of the pull-out effect of long fibers.
